Application March 28, 1946, Serial No. 657,787

1 Claim. (Cl. 215-73) This invention relates to a closure designed for bottles, tubes, or other containers, the primary object oi' the invention being to provide a closure which will be non-removable, and one which will permit the contents of the bottle or tube to pass therefrom in a straight unobstructed line.

Another object of the invention is to provide a device of this character wherein the size of the discharge opening may be varied by the closure, thereby regulating the flow of material from the bottle or tube.

Still another object of the invention is to provide a closure which will be fluid-tight when it has been positioned to close the discharge opening.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is an elevational view of a bottle constructed in accordance with the invention, the cap or closure thereof having been moved to its open position.

Figure 2 is a fragmental elevatlonal view of the neck of a bottle, showing the closure in its closed position.

Figure 3 is a longitudinal sectional view through the closure.

Figure 4 is an elevational view illustrating a removable closure attachment for use in connection with tubes.

Figure 5 is an elevational view illustrating a closure device in section, as in the form of an attachment to be used in connection with bottles.

Referring to the drawings in detail, the reference character 5 indicates a bottle which is provided with an offset upper portion 6 formed with an opening 6' which constitutes a continuation of the discharge opening through the bottle neck.

The upper portion 6 is offset at an oblique angle with respect to the side of the bottle, and is provided with a curved groove I formed in the outer surface thereof, the groove being designed to accommodate the pin 0, that is carried by the cap or closure 9 which is of a size to closely fit over the offset upper portion 6. A packing lining I0 is provided within the cap 9 to prevent leakage from the bottle between the bottle and cap, when the cap has been moved to its closed position, as shown by Figure 2 of the drawings.

From the foregoing it will be seen that due to this construction, the cap 9 may be moved to the position shown by Figure 1 of the drawings, to the end that the contents of the bottle may be poured in a direct line, from the bottle. It will also be noted that the cap is retained on the bottle at all times so that it may not become lost.

In the form of the invention as shown by Figures 4 and 5 of the drawings, the principle of the invention is carried out in the construction of an attachment for tubes or bottles, and as. shown, the reference character ll indicates a body portion having an enlarged end internal]; threaded at H) to fit over the threaded end Hi of the tube l3, the body portion being formed with a bore l2 that provides a continuation of the nozzle of the tube l3, on which it is positioned.

An enlargement It extends laterally from u 2 upper end of the body portion and this enlarge 1 ment is formed with a curved groove IE to r:

ceive the pin l6 carried by the cap l'l. Whe the cap is rotated, the pin li moving' in ti; 1 groove I5, will feed the cap to its closed pos tion. and by moving the cap to partially clo: the bore I2, the flow of material from the tut may be regulated.

The body portion shown by Figure 5 of ti drawings, and indicated by the reference cha1 acter I8, is substantially the same as that show by Figure 4 of the drawings, except that tl lower end of the body portion is flared as at I and provided with a gasket 20, to Permit it to l removably held on the mouth of a bottle. 1 this form of the invention the cap 2| moves 0V1 the enlargement 22 that extends laterally fro] the upper end of the body portion i8. Pin 2- carried by the cap 2|, moves in thecurved grooi 24 of the enlargement 22, to feed the cap to ii open or closed position, as the cap is rotated.

From the foregoing it will be seen that due t the packing l0, frictional contact will be set u; by the offset upper portion 6 and cap 9 to 1101i 3 the cap in various positions of adjustment along the ofl'set portion.

What is claimed is: In a bottle, an enlargement formed on the neck of the bottle adjacent to the mouth thereof, said enlargement being extended at an oblique angle with respect to the neck of the bottle, said neck having an unobstructed passageway disposed in a straight line axially therethrough to the mouth of the bottle, the wall of the passageway being in a straight line throughout the length of the neck, said enlargement having a curved external groove formed therein, a cap slidably mounted on the enlargement and being movable over the mouth of the bottle regulating theflow of material from the bottle, and a pin extending inwardly from the cap, the pin being disposed within the groove causing rotary movement of the cap on 4 the enlargement as the cap is moved longitudinally thereof.
